A flexible stand-up liquid pouch is formed from a sheet of foil film laminate material whereby opposed side walls of the material are folded together with sealed circumferential edges to form an enclosed chamber. A liquid is provided in the chamber, and the side walls of the sheet material which form the container have raised portions which, when sealed together, cooperatively form an internal straw restraining passage inside the container. The straw restraining passage communicates with the liquid chamber and a straw is held loosely captive inside the straw restraining passage and is axially displaceable therein. The straw restraining passage defines a reduced cross-sectional area of the chamber, and the pouch is manufactured with a weakened portion on an upper portion of the pouch, whereby the weakened portion can be torn by a user, thus enabling the internal straw to emerge, due to the buoyancy of the straw, from the interior of the pouch. In providing a sealed bottom edge to the liquid pouch, a bottom rim is formed, wherein the pouch can stand in an upright position on a horizontal surface upon the bottom rim.

PROBLEM TO BE SOLVED: To provide a cup which does not allow contents to spill out through a straw even if a container body is toppled. SOLUTION: The cup includes a bottle 1 formed to be a bottomed cylinder and a cap 2 for lidding an upper end opening of the bottle 1. The straw 4 made of a flexible material is made to protrude from an upper surface of the cap 2, and an opening at the tip of the straw 4 is closed by a closing wall 27. In addition, cuts 27 a and 27 b are formed on the wall 27. An over cap 3 which can slide along the upper surface of the cap 3 is mounted on the cap 2. When the over cap 3 is moved to one of sides, the straw 4 protrudes from the upper surface of the cap 2 to allow the contents to be sucked. When the over cap 3 is moved to the other side, the straw 4 is fallen by the over cap 3 and hidden below the over cap 3.

SUMMARY OF THE PRESENT INVENTION

The present invention discloses a disposable cup incorporating a slidably extendable retractable straw with a plurality of cups stackable through employment of a channel extending the length of the cup for encompassing the internal straw. A tubular member having an aperture on its lower end is disposed on the interior wall of the cup for slidably receiving the straw therein.

A primary object of the present invention is to provide a cup having an integral straw.

Another object of the present invention is to provide a cup having a tubular member fastened to the interior wall extending from the base of the cup to a point approximate the rim of said cup.

Yet another object of the present invention is to provide a cup wherein said tubular member has an aperture within its base forming means for the passage of fluid therein.

Still yet another object of the present invention is to provide a cup wherein said tubular member forms a sleeve that frictionally engages anther tubular member forming a straw movable within said sleeve.

Another object of the present invention is to provide a cup having a longitudinal channel formed in the exterior wall providing means for stacking one cup within another.

Yet another object of the present invention is to provide a cup wherein the extendable straw member resides below the rim of the cup in the retracted position.

Still yet another object of the present invention is to provide a cup wherein the extendable straw member can be selectively extended beyond the rim of the cup whereupon suction applied to the extended end draws fluid contained within the cup through said straw-like extension.

Another object of the present invention is to provide a cup wherein a lid can be fixed to the rim of the cup with the extendable retractable straw contained therein.

Additional objects of the present invention will appear as the description proceeds.

The present invention overcomes the shortcomings of the prior art by providing a disposable cup incorporating a slidably extendable retractable straw with a plurality of cups stackable through employment of a channel extending the length of the cup for encompassing the internal straw.
